The Record: 1936 — Present
What it promised
The end of the boom-and-bust catastrophe: government manages total demand — spending in the busts, restraining in the booms — delivering full employment and a smoothed cycle.
What it ran on
Countercyclical state spending, steered by technocrats. The fuel is fiscal capacity and the political will to use it in both directions — which, historically, meant one direction.
What it demanded of the worker
Trust. The worker's job was to trust the managers of demand, ride the cycle they smoothed, and absorb the inflation when the smoothing slipped.
What the wallet got
A genuine golden age — the postwar decades of shared growth happened substantially on Keynesian watch, and this file credits it. Then the 1970s delivered inflation and stagnation together, the one combination the model said shouldn't happen, and the framework never fully recovered its authority.
Where it was honest
Demand is real. Recessions are not moral punishments, and doing nothing during a collapse is a policy choice with a body count. That insight is permanent, and it was his.
The verdict
Scored 12.5 of 24. Keynesianism manages the cycle but never touches the structure: nothing in it connects the floor of a company to its ceiling. It can refill the pool; it cannot fix the plumbing that drains one end into the other. Fifty years of demand management coexisted with the ratio going from 21:1 to 285:1 — the cycle was smoothed while the extraction compounded.
Exhibit A — Their own best case, in their own words

The source itself: John Maynard Keynes, The General Theory of Employment, Interest and Money (1936), and Robert Skidelsky’s biography for the fair modern case. Keynes was the best mind on this shelf. He aimed at the cycle. We aim at the structure.
